JRush will Ichigo be able to put his hollow mask on via taunt because that could be how you activate his "Full Hollow" form. You would have to have the mask on then use your final smash since in the anime he died/lost even with his hollow mask on that's why he transformed full hollow outta desperation to save that girl.
I think kratos ground down b should be a counter (ik its played out but it fits him well) using his golden fleece. His air down b could be the hammer idea. Also I think his side b should be the boots of hermes move from mortal kombat.
